              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)

NOTE 1 - BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial reporting and in accordance with Form 10-Q and Rule 10.01 of
Regulation S-X. Accordingly, they do not include all of the information and
footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, the unaudited condensed
consolidated financial statements contained in this report reflect all
adjustments, which are normal and recurring in nature, considered necessary for
a fair presentation of the financial position and the results of operations for
the interim periods presented. The preparation of the Company's financial
statements in conformity with generally accepted accounting principles requires
management to make estimates and assumptions that affect the reported amounts of
assets, liabilities, revenues and expenses, as well as disclosures on contingent
assets and liabilities.  Because of inherent uncertainties in this process,
actual future results could differ from those expected at the reporting date.
These unaudited condensed consolidated financial statements, footnote
disclosures and other information should be read in conjunction with the
financial statements and the notes thereto included in the Company's Form 10K
filed with the Securities and Exchange Commission on March 25, 1997.

NOTE 2 - MEDICAL SERVICE REVENUE

Medical service revenue for services to patients by the medical groups
affiliated with the Company is recorded when services are rendered based on
established or negotiated charges reduced by contractual adjustments and
allowances for doubtful accounts.  Differences between estimated contractual
adjustments and final settlements are reported in the period when final
settlements are determined.  Medical service revenue of the affiliated medical
groups is reduced by the contractual amounts retained by the medical groups to
arrive at the Company's revenue.

The following presents the amounts included in the determination of the
Company's revenue (in thousands):

</TABLE>

In conjunction with the medical practice transactions occurring in the first
quarter of 1996, the Company is contingently obligated to pay up to an
additional $2.6 million in future years, depending on the achievement of certain
financial objectives.  Such liability, if any, will be recorded in the period in
which the outcome of the contingency becomes known.  Any payment made will be
allocated to the long-term management services agreements and will not
immediately be charged to expense.

For transactions completed through March 31, 1997, the scheduled issuance of the
shares of Common Stock that the Company is committed to deliver over the passage
of the time are:  1,816,858 in 1997, 2,940,617 in 1998, 5,244,319 in 1999,
5,092,384 in 2000, 1,298,859 in 2001 and 995,443 thereafter.  Although such
shares are not yet issued or outstanding, such shares are considered as
outstanding for per share calculations.

The accompanying unaudited condensed consolidated financial statements include
the results of operations derived from the management service agreements from
their respective effective dates.  The following unaudited pro forma information
presents the results of operations assuming all 1997 and 1996 transactions were
consummated on January 1, 1996.  Such pro forma information is based on the
historical financial information of the medical practices and does not include
operational or other changes which might have been effected pursuant to the
Company's management of the nonmedical aspects of such practices.

The pro forma information presented below is for illustrative information only
and is not necessarily indicative of results which would have been achieved or
results which may be achieved in the future (in thousands except share amounts):

</TABLE>

The Company has a loan agreement and revolving credit facility ("Credit
Facility") with First Union National Bank of North Carolina ("First Union")
individually and as Agent for seven additional lenders ("Lenders"), which was
amended as of October 30, 1996 to increase the amount available for borrowing
thereunder to $150 million through October 31, 2001.  Proceeds of loans may be
used to finance medical group transactions, provide working capital or for other
general corporate uses.  At March 31, 1997, the Company had an outstanding
balance of $45 million under the Credit Facility which consisted of multiple
draws with maturities up to 32 days.  The Company has classified this facility
as long term due to its ability and intent to renew the obligations through
1998.

Borrowings under the Credit Facility are secured by capital stock of the
Company's subsidiaries and all material contracts, including management service
agreements.  At the Company's option, funds may be borrowed at the Base interest
rate or the London Interbank Offer Rate plus a range from .5% to 1.5%
(determined under a specific formula).  Interest on amounts outstanding under
Base rate loans is due quarterly while interest on London Interbank Offer Rate
related loans is due upon maturity.  The weighted average interest rate
outstanding on draws under the Credit Facility at  March 31, 1997 was 6.58%.

The Company is subject to restrictive covenants under the facility, including
the maintenance of certain financial ratios.  The agreement limits certain
activities such as additional indebtedness, sales of assets, investments,

capital expenditures, mergers and consolidations and the payment of dividends.
Under certain circumstances, additional medical practice transactions may
require First Union and the Lenders' consent.

The Company has a $5,000,000 Master Lease Agreement to provide equipment
financing for use in operations.  At March 31, 1997, the Company had no
outstanding balance under the Master Lease Agreement.

NOTE 6- EARNINGS PER SHARE

The computation of earnings per share is based on the weighted average number of
Common Stock and Common Stock equivalent shares outstanding during the periods
in accordance with the requirements of the Securities and Exchange Commission
(SEC).  All options to purchase Common Stock, shares issued and commitments to
issue Common Stock at specified future dates are assumed to have been
outstanding Common Stock equivalents under the treasury stock method for each of
the periods presented.  Fully diluted earnings per share has not been presented
because it does not differ materially from the primary per share computations.

The table summarizes the determination of shares used in per share calculations

periods ending after December 15, 1997.  At that time, the Company will be
required to change the method currently used to compute earnings per share and
to restate all prior periods.

                    Management's Discussion and Analysis of
                 Financial Condition and Results of Operations


INTRODUCTION

American Oncology Resources, Inc. (the "Company") enters into management
agreements with, and purchases the nonmedical assets of, oncology medical
practices. Under the terms of the management agreements, the Company provides
comprehensive management services to its affiliated oncology practices,
including operational and administrative services, and furnishes personnel,
facilities, supplies and equipment. These practices provide a broad range of
medical services to cancer patients, integrating the specialties of medical
oncology, hematology and radiation oncology.  The Company's revenue consists of
management fees and includes all medical practice operating costs for which the
Company is contractually responsible.

In recent years, there has been a trend among oncologists to form larger group
practices that provide a broad range of services to cancer patients in
outpatient settings, rather than in hospitals or other inpatient settings.  The
Company believes that the coordinated delivery of comprehensive cancer care in
an outpatient setting offers high quality care that is more cost-effective than
traditional approaches and is increasingly preferred by patients, payors and
physicians.  The Company believes that many of these larger oncology practices
recognize the need for outside managerial, financial and business expertise to
more efficiently manage the increasingly complex, burdensome and time-consuming
nonmedical aspects of their practices and that such practices will increasingly
elect to enter into management relationships with entities such as the Company.

The Company's objective is to be the leading national physician practice
management company providing comprehensive services to an integrated network of
affiliated oncology practices.  The Company intends to achieve this objective by
(i) focusing exclusively on oncology, (ii) affiliating with leading oncology
practices throughout the United States, (iii) expanding each affiliated oncology
group's presence in its market, (iv) assisting affiliated oncology practices in
offering coordinated, comprehensive cancer care and (v) negotiating and
expanding managed care relationships.  Based on the Company's success in
expanding its business to date, the Company believes that it has effective
strategies for achieving its objective of becoming the leading national oncology
practice management company.

FORWARD LOOKING STATEMENTS

The statements contained in this report, in addition to historical information,
are forward looking statements based on the Company's current expectations, and
actual results may vary materially. The Company's business and financial results
are subject to various risks and uncertainties, including the Company's
continued ability to enter into affiliations with new physician practices and to
successfully integrate such practices, the results of operations of groups
currently affiliated with the Company, competition, reductions in third party
reimbursement for services rendered by physician groups affiliated with the
Company, health care regulation and other risks generally affecting the health
care industry. Please refer to the Company's 1996 Annual Report on Form 10-K for
a more detailed discussion of such risks and uncertainties. These forward
looking statements are provided as a framework for the Company's results of
operations. The Company does not intend to provide updated information other
than as otherwise required by applicable law.

RESULTS OF OPERATIONS

Since the Company's incorporation in October 1992, it has grown rapidly from
managing six affiliated physicians in one state to 250 affiliated physicians and
35 oncology practices in fifteen states as of March 31, 1997.  For the first
quarter of 1997 and 1996, only one of the Company's affiliated physician groups
contributed more than 10% of the Company's revenue which was 10% and 11%,
respectively, of total revenue.   For the first quarter of 1997, the payor mix
of the affiliated physician groups' medical practice revenue, expressed as a
percentage, was 33% for Medicare and Medicaid, 46% for managed care and 21% for
private insurance and other payors.  For the first quarter of 1996, the payor
mix of the affiliated physician groups' medical practice revenue, expressed as a
percentage, was 34% for Medicare and Medicaid, 45% for managed care, and 21% for
private insurance and other payors.   Because of the number of physician groups
with which the Company has recently affiliated and the different payor mix of
each affiliated physician group, meaningful year-to-year payor trends cannot yet
be identified.

1997 COMPARED TO 1996

  The Company amended management agreements to affiliate with four oncology
practices in the first quarter of 1997 and entered into new management
agreements with three oncology practices in the first quarter of 1996.  The
results of the new affiliated oncology practices are included in the Company's
operating results from the dates of affiliation.  Changes in results of
operations from the first quarter of 1996 to the first quarter of 1997 were
caused, in part, by affiliations with these oncology practices.

  Revenue.  Revenue for the first quarter of 1997 increased $29.6 million or 73%
over the comparable period of the prior year.  Of the increase in first quarter
revenue, $11.7 million was attributable to the addition of ten new oncology
practices with whom the Company entered into new management agreements after
March 31, 1996.  The remaining increase in revenue of $17.9 million for the
first quarter of 1997 was attributable to the increase in medical practice
revenue for affiliated physician practices with whom the Company entered into
management agreements prior to March 31, 1996.  Revenue for markets under
management in the first quarter of 1996 and 1997 increased 45% over the same
period from the prior year.  The methodology for calculating same market growth
is a change from the same practice growth disclosed in prior periods.  The
Company changed the methodology to more accurately reflect the revenue growth
for a market from period to period as well as the changing structure of new
physician transactions in 1997.  Under the new method, revenue growth for all
practices within a metropolitan service area in which the Company has operations
in both periods is treated as same market growth.  Under the old methodology,
the same practice growth for the first quarter of 1997 over the comparable
period in 1996 would have been a 34% increase in revenue.  The growth in
practice revenue resulted from the recruitment of new physicians, expansion of
services, affiliation with new physician groups, increases in patient volume
and, to a lesser extent, price adjustments for certain physician services.

  Pharmaceuticals and Supplies.  Pharmaceuticals and supplies, which include
drugs, medications and other supplies used by the affiliated physician
practices, for the first quarter ended March 31, 1997 increased $17.2 million or
115% over the comparable prior year peiod.  Of this increase, $6.1 million was
attributable to the addition of ten new oncology practices with whom the Company
entered into new management agreements after March 31, 1996.  The remaining
increase is principally the result of the expansion of services and increase in
patient volume of practices with whom the Company entered into management
agreements prior to March 31, 1996. As a percentage of revenue, pharmaceuticals
and supplies increased to 45.7% in the first quarter of 1997

                    Management's Discussion and Analysis of
                 Financial Condition and Results of Operations

from 36.7% in the first quarter of 1996. This increase was primarily due to a
shift in the revenue mix to a higher percentage of drug revenue, the
introduction of a number of new chemotherapy agents and, to a lesser extent,
lower reimbursement from payors. Management expects that third-party payors will
continue to negotiate medical services, pharmaceuticals (including chemotherapy
drugs) and other supplies, with the goal of lowering reimbursement and
utilization rates, and that such lower reimbursement and utilization rates as
well as shifts in revenue mix may continue to reduce the Company's margins with
respect to such items. The Company has adopted a number of strategies to address
this matter, including initiating preferred pharmaceutical relationships.

  Practice Compensation and Benefits. Practice compensation and benefits, which
include the salaries, wages and benefits of the employees of the affiliated
physician practices (excluding affiliated oncologists) and the employees of the
Company who are located at the affiliated physician practice sites, for the
first quarter of 1997 increased $5.1 million or 61% over the comparable prior
year period.  Of the increase for the first quarter of 1997, $2.1 million was
attributable to the addition of ten affiliated oncology practices with whom the
Company entered into new management agreements after March 31, 1996.  As a
percentage of revenue, practice compensation and benefits decreased to 19.1% in
the first quarter of 1997 from 20.5% in the first quarter of 1996.  Decreases in
practice compensation and benefit costs as a percentage of revenue resulted from
economies of scale.

  Other Practice Costs. Other practice costs, which consist of rent, utilities,
repairs and maintenance, insurance and other direct practice costs, for the
first quarter of 1997 increased $2.7 million or 53% over the comparable prior
year period.  Of the increase for the three months ended March 31, 1997, $0.9
million was attributable to the addition of ten affiliated oncology practices
with whom the Company entered into new management agreements after March 31,
1996.  As a percentage of revenue, other practice costs decreased to 10.9% in
the first quarter of 1997 as compared to 12.3% in the same period in 1996.
Decreases in other practice costs as a percentage of revenue resulted from
economies of scale.

  General and Administrative. General corporate expenses for the first quarter
ended March 31, 1997 increased $1.3 million or 45% over the comparable prior
year period.  This increase was primarily attributable to the addition of
personnel and greater support costs associated with the Company's rapid growth
since March 31, 1996.  As a percentage of revenue, general and administrative
expenses decreased to 5.9% in the first quarter of 1997 from 7.1% in the first
quarter of 1996, primarily as a result of economies of scale.

  Depreciation and Amortization. Depreciation and amortization expenses for the
quarter ended March 31, 1997 increased $1.1 million or 60% over the comparable
prior year period.  This increase was primarily the result of amortization of
intangible assets associated with the Company's entering into new and amending
existing management agreements with physician groups.

  Interest.  Net interest expense increased to $1.6 million for the first
quarter of 1997 from $0.5 million in the same period of 1996.  The increase was
primarily attributable to interest expense on borrowings used to fund  cash
consideration and physician debt issued for seventeen medical practice
transactions, including both new and amendments to existing management
agreements, since March 31, 1996.  In the future, management expects that net
interest expense as a percentage of revenue will increase slightly due to
anticipated debt related to medical practice transactions and the development of
integrated cancer centers.

  Income Taxes. For the first quarter of 1997 and 1996, the Company recognized a
tax provision of $3.2 million and $2.7 million, respectively, at estimated
annual effective rates of 38.5% and 38.0%, respectively.   The effective annual
tax rates represent management's best estimate of the tax provision based on the
existing state revenue mix.

                 Financial Condition and Results of Operations

LIQUIDITY AND CAPITAL RESOURCES


  The Company requires capital primarily to enter into new or amended management
agreements with, and to purchase the nonmedical assets of, oncology medical
practices.  During the quarter ended March 31, 1997, the Company paid total
consideration of $29.4 million for the affiliation of four oncology practices
through amending existing management agreements, including cash and transaction
costs of $13.9 million.  During the comparable period of the prior year, the
Company paid $31.3 million for management agreements with physician groups
including cash and transaction costs of $19.4 million.

  To fund this rapid growth and development, the Company has satisfied its
transaction and working capital needs through a recapitalization, private debt
and equity financings, and borrowings under a $150 million syndicated revolving
Credit Facility with First Union.  The Company has relied primarily on
management fees received from its affiliated physician practices to fund
operations.  Cash derived from operations was $12.4 million for the first
quarter of 1997, while cash used in operations in the comparable period of 1996
was $1.5 million.  The increase is due primarily to the operations of the
oncology practices with whom the Company has affiliated since March 31, 1996,
and the effect of the reversal of the accelerated payments made in December 1996
to the affiliated physician groups.

  During the first quarter of 1997, the Company borrowed $32 million under the
Credit Facility to fund medical practice transactions and the purchase of
treasury stock.  Of the 1997 borrowings, $10 million was repaid during the
quarter.   Borrowings under the Credit Facility bear interest at a rate equal to
a rate based on prime rate or the London Interbank Offer Rate, based on a
defined formula.  The Credit Facility contains affirmative and negative
covenants, including the maintenance of certain financial ratios, restrictions
on sales, leases or other dispositions of property, restrictions on other
indebtedness and prohibitions on the payment of dividends.  The Company's
management service agreements, its equity ownership in its subsidiaries and all
other securities owned by the Company (other than treasury shares of the
Company) are pledged as security under the Credit Facility.  The Company is
currently in compliance with the Credit Facility covenants.


  At March 31, 1997, the Company had working capital of $48.0 million and cash
and cash equivalents of $8.6 million.  The Company also had $39.5 million of
current liabilities, including approximately $5.2 million of short term notes
payable and long-term indebtedness maturing before March 31, 1998.  The Company
currently expects that its principal use of funds in the near future will be in
connection with anticipated transactions with affiliated physician groups, the
purchase of medical equipment and the acquisition of real estate for the
development of integrated cancer centers.  The Company expects that the existing
cash and investment balances, cash generated from operations and amounts
available under the Credit Facility will be adequate to satisfy the Company's
cash requirements for the next 12 months.

        Section 2.02.  Annual Meeting.  The annual meeting of stockholders shall
be held, unless the Board of Directors shall fix some other hour or date 
therefor, at 11:00 o'clock A.M. on the third Monday of April in each year, if

the next succeeding secular day not a legal holiday under the laws of Delaware, 
at which the stockholders shall elect by plurality vote a Board of Directors, 
and transact such other business as may properly be brought before the meeting.

        Section 2.03.  Notice of Annual Meetings.  Written notice of the annual 
meeting stating the place, date and hour of the meeting shall be given to each 
stockholder entitled to vote at such meeting not less than 10 days nor more

<PAGE>
 
meeting is to be held, which place shall be so specified in the notice of the 
meeting, or, if not so specified, at the place where the meeting is to be held. 
The list shall also be produced and kept at the time and place of the meeting 
during the whole time thereof, and may be inspected by any stockholder who is 
present.

        Section 2.05.  Special Meetings.  Special meetings of the stockholders, 
for any purpose or purposes, unless otherwise prescribed by statute or by the 
Certificate of Incorporation, may be called by the Chairman of the Board or the

writing of a majority of the Board of Directors.  Such request shall state the

meeting of stockholders shall be limited to the purposes stated in the notice.

        Section 2.06.  Notice of Special Meetings.  Written notice of a special

issued and outstanding and entitled to vote thereat, present in person or 
represented by proxy, shall constitute a quorum at all meetings of the

statute or by the Certificate of Incorporation.  If, however, such quorum shall
not be present or represented at any meeting of the stockholders, the 
stockholders entitled to vote thereat, present in person or represented by 
proxy, shall have power to adjourn the meeting from time to time, without notice
other than announcement at the meeting, until a quorum shall be present or 
represented.  At such adjourned meeting at which a quorum shall be present or 
represented any business may be transacted which might have been transacted at 
the meeting as originally notified.  If the adjournment is for more than thirty 
(30) days, or if after the adjournment a new record date is fixed for the 
adjourned meeting, a notice of the adjourned meeting shall be given to each 
stockholder of record entitled to vote at the meeting.  When a quorum is present
at any meeting, except for elections of directors, which shall be decided by 
plurality vote, the vote of the holders of a majority of the stock having voting
power present in person or represented by proxy shall decide any question 
brought before such meeting, unless the question is one upon which by express 
provision of statute or of the Certificate of Incorporation, a different vote is
required, in which case such express provision shall govern and control the 
decision of such question.  Unless otherwise provided in the Certificate of 
Incorporation, each stockholder shall at every meeting of 

                                      -2-

stockholders be entitled to one vote in person or by proxy for each share of the
capital stock having voting power held by such stockholder, but no shares shall 
be voted pursuant to a proxy more than three (3) years after the date of the 
proxy unless the proxy provides for a longer period.

        Section 2.08.  Action Without a Meeting.  Unless otherwise restricted by
the Certificate of Incorporation, any action required or permitted to be taken 
at any annual or special meeting of stockholders may be taken without a meeting,
without prior notice and without a vote, if a consent or consents in writing 
setting forth the action so taken shall be signed by the holders of outstanding 
stock having not less than the minimum number of votes that would be necessary 
to authorize or take such action at a meeting at which all shares entitled to 
vote thereon were present and voted and shall be delivered to the Corporation by
delivery to its registered office in the State, its principal place of business,
or an officer or agent of the Corporation having custody of the book in which 
proceedings of meetings of stockholders are recorded.  Delivery made to the 
Corporation's registered office shall be by hand or by certified or registered 
mail, return receipt requested.  Every written consent shall bear the date of 
signature of each stockholder who signs the consent and no written consent shall
be effective to take the corporate action referred to therein unless, within 
sixty days after the earliest dated consent delivered in the manner required by 
this Section to the Corporation, written consents signed by a sufficient number 
of stockholders to take action are delivered in the manner required by this 
Section to the Corporation.  Prompt notice of the taking of the corporate action
without a meeting by less than unanimous written consent shall be given to those
stockholders who have not consented in writing.

                                   ARTICLE 3

        Section 3.01.  Number and Term of Office.  The number of directors of 
the Corporation shall be such number as shall be designated from time to time by
resolution of the Board of Directors and initially shall be one.  The directors

his earlier death, resignation or removal.  Directors need not be stockholders.

        Section 3.02.  Vacancies.  Vacancies and newly created directorships 
resulting from any increase in the authorized number of directors may be filled

the next annual election and until their successors are duly elected

                                      -3-

<PAGE>
 
and shall qualify, unless sooner displaced.  If there are no directors in 
office, then an election of directors may be held in the manner provided by 
statute.  If, at the time of filling any vacancy or any newly created 
directorship, the directors then in office shall constitute less than a 
majority of the whole board (as constituted immediately prior to any such 
increase), the Court of Chancery may, upon application of any stockholder or 
stockholders holding at least 10 percent of the total number of the shares at 
the time outstanding having the right to vote for such directors, summarily 
order an election to be held to fill any such vacancies or newly created 
directorships, or to replace the directors chosen by the directors then in 
office.

        Section 3.03.  Resignations.  Any director may resign at any time by 
giving written notice to the Board of Directors, the Chairman of the Board, if 
there is one, the President, or the Secretary.  Such resignation shall take 
effect at the time of receipt thereof or at any later time specified therein; 
and, unless otherwise specified therein, the acceptance of such resignation 
shall not be necessary to make it effective.

        Section 3.04.  Direction of Management.  The business of the Corporation
shall be managed under the direction of its Board of Directors, which may 
exercise all such powers of the Corporation and do all such lawful acts and 
things as are not by statute or by the Certificate of Incorporation or by these 
Bylaws directed or required to be exercised or done by the stockholders.

        Section 3.05.  Place of Meetings.  The Board of Directors of the 
Corporation may hold meetings, both regular and special, either within or 
without the State of Delaware.

        Section 3.06.  Annual Meeting.  Immediately after each annual election 
of directors, the Board of Directors shall meet for the purpose of organization,
election of officers, and the transaction of other business, at the place where 
such election of directors was held or, if notice of such meeting is given, at 
the place specified in such notice.  Notice of such meeting need not be given.  
In the absence of a quorum at said meeting, the same may be held at any other 
time and place which shall be specified in a notice given as hereinafter 
provided for special meetings of the Board of Directors, or as shall be 
specified in a written waiver signed by the directors, if any, not attending and
participating in the meeting.

        Section 3.07.  Regular Meetings.  Regular meetings of the Board of 
Directors may be held without notice at such time and place as shall from time 
to time be determined by the Board.

        Section 3.08.  Special Meetings.  Special meetings of the Board of 
Directors may be called by the Chairman of the Board, if there is one, or the 
President on two (2) days' notice

                                      -4-

to each director; either personally (including telephone), or in the manner 
specified in Section 4.01; special meetings shall be called by the Chairman of 
the Board, if there is one, or the President or the Secretary in like manner and
on like notice on the written request of two (2) directors.

        Section 3.09.  Quorum; Voting.  At all meetings of the Board, a majority
of the directors shall constitute a quorum for the transaction of business; and 
at all meetings of any committee of the Board, a majority of the members of such
committee shall constitute a quorum for the transaction of business.  The act of
a majority of the directors present at any meeting of the Board of Directors or 
any committee thereof at which there is a quorum present shall be the act of the
Board of Directors or such committee, as the case may be, except as may be 
otherwise specifically provided by statute or by the Certificate of 
Incorporation.  If a quorum shall not be present at any meeting of the Board of 
Directors or committee thereof, the directors present thereat may adjourn the 
meeting from time to time, without notice other than announcement at the 
meeting, until a quorum shall be present.

        Section 3.10.  Action Without a Meeting.  Any action required or 
permitted to be taken at any meeting of the Board of Directors or of any 
committee thereof may be taken without a meeting, if all members of the Board or
committee, as the case may be, consent thereto in writing, and the writing or 
writings are filed with the minutes of proceedings of the Board or committee.

        Section 3.11.  Participation in Meetings.  One or more directors may 
participate in any meeting of the Board or committee thereof by means of

resolution passed by a majority of the whole Board, designate one or more 
committees, each committee to consist of one or more of the directors of the 
Corporation.  The Board may designate one or more directors as alternate members
of any committee, who may replace any absent or disqualified member at any 
meeting of the committee.  Any such committee, to the extent provided in the 
resolution, shall have and may exercise all of the powers and authority of the 
Board of Directors and may authorize the seal of the Corporation to be affixed 
to all papers which may require it, but no such committee shall have the power 
or authority in reference to amending the Certificate of Incorporation (except 
that a committee may, to the extent authorized in the resolution providing for 
the issuance of shares of stock adopted by the Board of Directors, fix any 
preferences or rights of such shares relating to dividends, redemption,

        Section 6.04.  Other Rights.  The indemnification and advancement of

Directors may, in its discretion and as a condition precedent to the issuance 
thereof, require the owner of such lost, stolen or destroyed certificate or 
certificates, or his legal representative, to advertise the same in such manner

direct as indemnity against any claim that may be made against the Corporation

for the purpose of any other lawful action.  Such record date shall not precede

or other claim to, or interest in, such stock on the part of any other person,
